Data for manuscript entitled "Quantum-limited optical time transfer for future geosynchronous links"

Data provided by  National Institute of Standards and Technology

Data for the figures in the manuscript entitled "Quantum-limited optical time transfer for future geosynchronous links" first published as a preprint at https://arxiv.org/abs/2212.12541. Abstract: The combination of optical time transfer and optical clocks opens up the possibility of large-scale free-space networks that connect both ground-based optical clocks and future space-based optical clocks. Such networks promise better tests of general relativity, dark matter searches, and gravitational wave detection.

Dual electro-optic frequency comb photonic thermometry

Data provided by  National Institute of Standards and Technology

Data from peer-reviewed publication: A. J. Fleisher et al., Dual electro-optic frequency comb photonic thermometry, Optics Letters. We report a precision realization of photonic thermometry using dual-comb spectroscopy to interrogate a ?-phase-shifted fiber Bragg grating. We achieve read-out stability of 7.5 mK at 1 s and resolve temperature changes of similar magnitude?sufficient for most industrial applications.

ns-3 ORAN Module

Data provided by  National Institute of Standards and Technology

This module for ns-3 implements the classes required to model a network architecture based on the O-RAN Alliance's specifications. These models include a Radio Access Network (RAN) Intelligent Controller (RIC) that is functionally equivalent to O-RAN's Near-Real Time (Near-RT) RIC, and reporting modules that attach to simulation nodes and serve as communication endpoints with the RIC in a similar fashion as the E2 Terminators in O-RAN.

High-volume, label-free imaging for quantifying single-cell dynamics in iPSC colonies

Data provided by  National Institute of Standards and Technology

This collection is comprised of multiple sets of experiments involving iPSCs with varying dosages of fluorescent light excitation. Samples were imaged every 2 minutes using phase-contrast microscopy for 20+ hours with or without fluorescence excitation. Each experiment was done on different days (i.e. exp0 vs exp1) but with triplicate wells (i.e. exp1-0, exp1-1, exp1-2). Additionally, data used to train our 2D U-Net and 3D U-Net models are included. Detailed information for each dataset can be found in Dataset_Information.xlsx.

Trojan Detection Software Challenge - object-detection-feb2023-train

Data provided by  National Institute of Standards and Technology

Round 13 Train DatasetThis is the training data used to create and evaluate trojan detection software solutions. This data, generated at NIST, consists of object detection AIs trained both on synthetic image data build from Cityscapes and the DOTA_v2 dataset. A known percentage of these trained AI models have been poisoned with a known trigger which induces incorrect behavior. This data will be used to develop software solutions for detecting which trained AI models have been poisoned via embedded triggers. This dataset consists of 128 AI models using a small set of model architectures.

Data Publication: Data from NIST IR "Report on VAMAS Round Robin of ISO 13067: Microbeam Analysis - Electron Backscatter Diffraction - Measurement of Average Grain Size"

Data provided by  National Institute of Standards and Technology

This data publication includes electron backscatter diffraction (EBSD) data used to support the development of ISO 13067 "Microbeam Analysis - Electron Backscatter Diffraction - Measurement of Average Grain Size" as part of a Versailles Project on Advanced Materials and Standards (VAMAS) work area. EBSD data was collected on two commercially pure titanium samples. Two different scanning electron microscopes were used, and two staff independently performed measurements of 5 selected areas.
